Specification of Letters Patent.

Patented Oct. 24, 1916.

Application filed June 19, 1913; Serial No. 774,560. Renewed September 5, 1916. Serial No. 118,550.

To all whom it may concern:

Be it known that I, LEWEN R. NnLsoN, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Lawn-Sprinklers, of which the following is a specification.

My invention relates to certain new and useful improvements in lawn sprinklers.

The purpose of my invention is to provide a sprinkler body adapted to sprinkle an area less than a complete circle, with a view of leaving a clear space at the inlet or rear-portion of the sprinkler body that will provide a clear approach for the user. i A further object of my invention is to more uniformly sprinkle a given area than would be the case ifbut one row of discharge openings were provided in the sprinkler body, and to this end I provide the relativelyplaced partial circles of openings disposed in different arcs, also I obtain a broad base and reduce cost materially.

My invention consists in constructing a sprinkler body with a portion preferably partially circular and havingsubstantially vertical walls, and with a substantially straight cross portion connecting and com municating with the circular part, and likewise having substantially vertical walls, thereby gaining strength from very light material and providing a large interior open space surrounded by said walls which will give the body an extended base-support. The curved and straight portions of the sprinkler body are designed to be united to form a continuous interior channel as disclosed. In connection with the circular portion of the body, a series of perforations is provided, preferably describing an arc substantially co-extensive therewith, and a series of perforations is also provided within the rear transverse portion, preferably disposed in arc shape, as above indicated. The trans verse or rear section of the sprinkler body may be provided with a raised portion in its upper face adjacent the inlet and the perforations may be provided therein so as to cause a discharge forwardly and laterally with relation to the sprinkler body.

My invention may be applied to a circular body by arranging the discharge perforations to comprehend only a portion of the circle described by such body, and by arranging another series of perforations rearwardly of the aforesaid perforations, whereby substantially the same effect may be obtained as in the first mentioned plan.

Referring to the drawings, Figure 1 is aplan view of one form of my invention; Fig. 2 is a sectional view on the line 22 of Fig. 1, Fig. 3 is a plan view of another form of my invention, and Fig. 4 is a sectional view on the line 44 of'Fig. 3. I

i I am aware of the fact that in the sprinkler art, it is not new to arrange the discharge openings in the sprinkler head in such a manner as to accomplish a discharge in advance ofthe sprinkler head, leaving the rear portion thereof approachable, as I am the applicant for a patent at the present time upon such a type of sprinkler head, and furthermore, the company with which I am associated, is the owner of the patent to Chas. Ballreich, No. 943,172, dated Dec. 14, 1909, which I believe, contains the first sugges'tion of this plan, but I find from experience that under certain conditions of use, a sprinkler head constructed in pursuance of the Ballreich patent, if made with a reasonable saving of material, is too small and has not sufiicient bearing surface to maintainit in the proper contact with the ground surface, as it is liable to tip through the torsion of the hose. By enlarging the circle, I increase the surface contact of the sprinkler body and reduce the amount of material necessary to be used, by cutting out the central body portion, leaving a large central opening, furthermore, by obstructing the inflow opposite and near to the inlet I am able to get a stronger discharge through openings near the inlet than if the head were entirely open as in Ballreich.

Referring to the drawings, 2 denotes generally the sprinkler head. It is preferably formed of sheet metal, but may be cast, and comprises a substantially are shaped part 3 and a substantially rectangular portion 4 extending transversely of the sprinkler head and meeting the walls of the are shaped part 3 to complete a continuous passageway within the shell that produces the sprinkler body. The are shaped portion of the sprinkler body has the forwardly inclined wall portion 5 extending thereabout, which portion is perforated as at 6, throughout substantially the entire arc, which disposition of the discharge openings effects a discharge perforations causes a discharge entirelyabout the are shaped portion of the, spnin; kler head, both in front and at the sides,

leaving the rear portion of the sprinkler head approachable.

7 1s asemic rcular raised portion struck up from the body of the cross section I of the sprinkler andI provide perforations as 8 about the said raised portion, arranging the same in arc form, as disclosed, serving through the formationof, the raised, portion and the arc shaped, disposition of the openings, to accomplish a discharge of water'in part, thereby accomplishing a more thor ough and equal distribution thereof.

I may vary the extent and form of the raised portion 7 to cause it to comprehend a, greater or less portion of the transverse part, at and may similarly increase. or diminish the number of discharge. openings within said raised portion to suit conditons of use for which the sprinkler head may be designed,

I provide the raised portion 7 for the ad;-

ditional purpose of providing a. seat and clearance for the threaded inlet portion 9. It will be noted that in the disclosure made of my structure, the wall portion of the sprinkler body is of, substantially uniform height and "size, but in practice I am able, because ofthe enlargement of the sprinkler body as at 7, which takes care of andpro vides space for the proper placing of the inlet, to reduce the size of the remaining portion of the sprinkler body materially so that it will not need to stand so highQfrQm base to top, thus accomplishinga material saving in cost of production and a corresponding lessening of the cost to the user.

In Figs. and 4 I have shown my-inventi on in a somewhat different embodiment fromthat disclosed in the other figuresof the drawing. This modified construction involves the same principle and the same, functional sprinkling results are sought; to be obtained as in the other figures, "In this modified form, 10 refers generally tothe sprinkler body. It comprises lower section 11, and upper section l2 joinedtogether in a manneiyto; provide a water passageway 13. The upper, outer edge of the sprinkler body isinclined asat ll forthe same purposes as described in connection with the disclosure in Figs l and). Perforations aredisposed within the inclined wall portion throughout a portion of the circle described by I the le Eb i' o tha a s h semay. n fiec e at right angles from the inlet as wellas in frontof the same. I provide the raised portion15-and provide the perforations in arc arrangement for the same purposes as in the structure previously described, the only difference between the two structures being that of form.

Realizing that the principle involved and the results obtained may be" reached by other embodiments than those disclosed herein, I do not limit myself to. the particuwall of the straight channel; in. rear of the first mentioned inclined portion, and a series of perforations in each of. said, inclined walls adapted. to discharge over a surface in advance of the straight channel.
